Extreme Stacking Backup Node Reboot

Colleagues, good afternoon . Prompt
please, there is such problem - if one of switches in a stack (master) is overloaded that the second node backup is overloaded after it through
10-15 seconds. And this in my opinion is some nonsense. Have you encountered such behavior of the stack and can it be defeated?

On the X670G2-48x and G670G2-72x stack, the license level on both switches is the same, both have master capability enabled.

1. What EXOS version?
2. Is there some messages appear in logs?
3. What sys-recovery level configured?
4. Is both nodes powered by same UPS? Is backup node rebooting when power off manually Master node?
5. As I understand Master node was changed from 00:04:96:98:79:f9 to 00:04:96:a0:7f:9d?

please write a scenario of what is happening. as it stands it appears you are unplugging the master, and testing failover, but when you do this it reboots the standby node? is this correct?

log in to the secondary switch and view the log messages. see if you can post those here, we would need the switch to tell us why it felt the need to reboot.

I do know that it is common issue for the whole stack to reboot if 2 switches are in state Master ( the log will state "dual Master" and reboot the whole stack.

I have seen this when the master stacking modules fail. the switch stays running, but the links between switches flicker/ bounce sending the stack in to dual master... the whole stack fails and reboots.

so I would check the cables you have between the switches to see if either of them are having issues.
